    I am running a stock Dauntless V6 Engine in a 1968 CJ 5. I am moving he jeep from Ohio to Telluride CO. The jeep is going to be running in elevations that range from 7000'-12500'. What size Jet do I need for the carb. Any info would be great. Thanks!

    Average is dropping 1 jet for every 2K up in Elevation - I set all my stuff for 10K and lower the float a touch - seems to work fine for me (even when I had a stock Dauntless).

    Thanks for the info. I really appreciate it. My jeep should be ready by the end of the week. When I get a digital camera I will post some photos of it. Totally stock totally renovated top to bottom CJ 5 with 12,000 miles on it. She is beautiful I think folks on this board will really appreciate it.

    Ok,
    does anyone else know a good supplier for these jets. I do not have the jeep with me, but I do know that it is the stock carb that came on the Dauntless so I want to make sure I am ordering the proper ones. The links above did not work out. Any one got any sources?
